I agree that the truth isn't subject to change. Facts are what they are, regardless of when they're being view or by whom.

Morality, however, isn't a fact. It's a subjective opinion. Even when it comes to you via the bible. Even if it's precisely the same bible with the same verbiage as the one read by your ancestor 200 years ago. Even if it's the same one as read by your neighbor today. All three of you will come up with different moral interpretations from the same words.

Facts are facts... until they are filtered through the human consciousness. Then they become highly modified and personalized judgements.

Which is why some christians won't ever being viewing your words through the computer for fear of this demonic use of electricity. And why some christian women who are beaten by their husbands have no recourse. And why some christians still keep the sabbath on Saturday. And why some christians abstain from alcohol. Etc.

Yes, the truth is always the truth. Until one human attempts to convey the truth to another human. Then you get two truths.
